Lots of good stuff on this car, I think?

How much do you think it'll go for.

Some really stupid paint in places it doesn't belong.

Porsche racing engines of that era often got more out of a three litre. The carbs , cams and free flow exhaust can do it.
Need a robust 915 to handle the power

which it appears to have. The “shortest” 1st gear we do is a 2.78. That’s compared to a 3.818 1st. What this allows us to do it also move 2nd and 3rd taller than stock while simultaneously making them closer together. This makes the distance from the root of the tooth of the gear to the ID greater and therefore stronger. If people are interested in seeing the differences I can post some pictures when I’m at my office tomorrow.

The ad mentions installing milder cams. I wonder if the dyno pull was before or after the surgery?

the way I read it the pull was before the change.

'73 RSR 911/52 engine - 300 hp, but only at 8,000 rpm

you don't want to drive it on the street and you DO want to rebuild it after every race

if this car has great EFI, 0.2 more L, and Direct FI, then...
